playSound not Functioning

[DrakeStoel]

So I've run into an interesting problem. I set up a simple playSound function. It works like this:

Collision --> On any side of: Player, Repeat while actor is colliding?: No --> playSound

This should work (unless I'm really REALLY missing something) but when I make my player walk into the collision object, nothing happens. What am I doing wrong? There are no other sounds or music playing at the time. Please help!

Hi! I'll try to help you

There is many possible causes for the problem you are facing. If you could answer these few questions it'd be easier to try to find out what is causing the sound not to play.

What system are you on? Linux, Windows, Mac? There is differences between GE's audio support on these platforms.

What file type is the sound file you're trying to play? GE doesn't support sound files, for a list of supported files search the Game Editor wiki.

What version of Game Editor are you using? Also, have you tried using playSound2 instead?

Thanks!

I have Windows 7. The file is .wav, and I'm using gameEditor Beta v1.4.1.

I've tried using playSound2, as both the regular function, and by using a variable to give it it's own sound channel.

I've made a discovery though. When my all of the events of my player actor are disabled, the sound plays, so I've been trying to hunt down the culprit but haven't had any luck yet.

Ok! I found the problem, but I don't understand it.

So I have this fairly cluttered bit of code (I'm sure there's a more efficient way to do all this, but it works for now ) and the problem is under the "if(swamp == 0)" branch. It's the stopSound function (which I have nullified).

I don't understand why this one event would stop all other sounds not related to the player actor (I tried having other actors make sounds, but none worked before the tweak). I have been under the impression that giving a sound it's own integer, it shouldn't effect the other sounds currently playing.

Code: Select all

switch(attack)
{
// Not Attacking
case 0:
// Key Test
attack = (key[KEY_x]==1);
nkeys = key[KEY_LEFT]+key[KEY_RIGHT]+key[KEY_UP]+key[KEY_DOWN];
// Set Direction & Speed

if (swamp == 0)
{
dir = (1*key[KEY_UP]+2*key[KEY_LEFT]+3*key[KEY_DOWN]+4*key[KEY_RIGHT])*(nkeys<2);
player_collide.angle = dir*90;
player_collide.directional_velocity = 3*(dir>0);
    //stopSound(SFXSwampWalk);
    DestroyTimer("SwampWalk");
}
else if (swamp == 2)
{
   dir = (1*key[KEY_UP]+2*key[KEY_LEFT]+3*key[KEY_DOWN]+4*key[KEY_RIGHT])*(nkeys<2);
   player_collide.angle = dir*90;
   player_collide.directional_velocity = 2*(dir>0);
}
else if (swamp == 1)
{
dir = (1*key[KEY_UP]+2*key[KEY_LEFT]+3*key[KEY_DOWN]+4*key[KEY_RIGHT])*(nkeys<2);
player_collide.angle = dir*90;
player_collide.directional_velocity = 1.5*(dir>0);
if (player_collide.directional_velocity == 0)
{
    stopSound(SFXSwampWalk);
    DestroyTimer("SwampWalk");
}
}

It's funny because the idea behind this code still works as intended, so it's even more strange to me...

What value does the variable SFXSwampWalk have? If it's 0 that will make it stop all sounds. Have you tried if the same problem occurs with Game Editor 1.4.0?

[DrakeStoel]

Oooooooohhhhhhhh... I'm now thinking I don't actually understand how sounds as variables work

So this is how I thought it worked:
Setting up the variable:
Global Code -> Vars

Code: Select all

int SFXSwampWalk

and the activation event
Collision->Any Side of (player)->Script Editor:

Code: Select all

SFXSwampWalk = playSound2 (blah blah blah);

But from your question, I feel like that is very wrong because I don't have it set as a number, rather a different function.

Also, I have tried it in older versions, but none of them seem to be backwards compatable and I keep getting the message: This needs the latest version of gameEditor to open (or something similar)

No, you haven't understood anything wrong, that is how you're supposed to catch the sound channel used by the sound.

Code: Select all

SFXSwampWalk = PlaySound2(...);

This code is correct, it plays the sound and stores what PlaySound2 returns into the SFXSwampWalk variable. And PlaySound2 returns the number of the channel used, so that's right. You're not setting SFXSwampWalk to the function, don't worry. I'm sorry I made you confused with my question.

What I meant to do was to ask what value the variable gets - e.g. to ask you to check that by using a text actor to show the value of SFXSwampWalk. If PlaySound2 fails it will return 0 instead of the channel number. And that could then result in stopSound being called with the value 0, thus causing it to stop all sounds in the game.

I could also take a look at the .ged if you'd like.

[DrakeStoel]

Oh, ok. Sorry, I think it's me to blame! I didn't quite understand the question. I read through it pretty quickly

Anyways, I set up the text actor, and interestingly enough, it was switching between 2 and 3. My theory is that it is because I have it set to loop on a timer because I couldn't figure out a better way without it interrupting... Something... I can't remember what though And it's just switching quickly between the two channels to compensate?

I checked the other sounds (ie opening doors, getting keys, etc.) and they were also returning two. And these numbers were all the same, both with the original code, and the edited one.

It really isn't a problem now, it all works fine. It's just oddly frustrating not knowing why it doesn' work

Okay. But yeah, I'd also like to know why it won't work.
